REFRIGERATOR OR CABINET.

Application filed March 19, 1926 Serial No. 95,898.

' the tendency of the joints to pull away. I

q}uite uniformly successful have also heretofore proposed to cover the outside of a cabinet or refrigerator with a coating of oxychloride cement on which is placed the finishing enamel. This has been but in some cases, t 1e boxes, which are ordinarily constructed ofredwood, shrink or expand and cause the stretching or breaking of the enamel and the stone coating.

It is the object of the present invention to provide a coating for cabinets and refrigerators which will permit a slight shifting of the wood orthe material of which the box is constructed without tending to break or crack the ornamental finished coat of enamel or stone. A further object is to so reinforce the enamel or the stonework that it is not so subject to fracture or checking.

In .the drawings:

Fig. 1 is a perspective view partly in section, showing a refrigerator W1th a stonework coating involving mynew unprovement. v

Fig. 2 is a detail stonework.

Fig. 3 is a detail section of a modified form of coating.

In Fig. 1 is shown a perspective view of a refrigerator coated with my new lmproyement. It has the several chambers which includethe food chamber or chambers, and the'ice chamber or'refrigerating unit chamber. The inside lining of the refrigerator is preferably a casting, of an oxy-chloride cement and sand mixture to form a unit stonework lining. This is molded directly on the insulation which is designated a and which comprises cork boards that are nailed or fitted onto the inside of the wooden box which forms the cabinet structure. The box is designated 7). It is preferably constructed of California redwood which I find has the least volume change of anywood with which I have e r mee svoe a b x rv s section of the coating of be too great.

to reinforce the stonework lining, and also the stonework which is to be applied to the outside.

On the outsideof the box I preferably spray or paint an. oxy-chloride cement! This oxy-chloride cement comprises powdered magnesium oxide which is mixed wit-h sufIicient magnesium chloride in asolution of 26 -Baum' to make the resulting mixture thin enough to spray. This oxy-chloride cement has a great affinity for wood, and especially this California redwood. 'Thiscoating is designated c. I then spread over this wet coatmg a. EIPIIC, preferably muslin. After this has been done I then spray the muslin covered box with another coatingofoxy-chloride cement of practically the same ingredients. This coating is designated d. I thenlfind it desirable tospray the finishmg coating over the oxy-chloride cement after the same is dried and hardened. "This i may be a paint, but is preferably some air drying enamel, such as one of the well known pyroxylin finishes.

I find that a coating so applied to a cabinet will not break or'crack as is the ,case .witl1 a coating that is fragile and which is applied directly to the wood. -The muslin or fabric interlaid between the layers of the oxy-chloride cement permits volume changes to take place in the redwood and allows the small amount of shifting when the joints expand or shrink slightly This prevents the fracture of the outside coating of the stone and the enamel. The" oxy-chloride cement is Very tenacious whenapplied to the fabric. In fact, it cannot ordinarily be separated-from the fabric after it has hardened. 'Thefabric not only permits a. certain amount of shifting of the under coat but gives the outside coat great tensile strength as compared with the ordinary frangibility of a material of this character; hence, even if it be subjected to stresses it will tend to resist these unless they Although the foregoing is my preferred construction, I find that measurably good results can be obtained in other ways-the first coat applied to the wood may be a coat of glue, or similar binding, and is designated 6 (Fig. 3). A fabric of muslin 0r Qt-her mate rial .is then laid over the glue. Onto this may be placed a sizing and then any suitable enamel may be painted or sprayed onto the sizing, but preferably some air-drying enamel or paint. I do not wish to be strictly limited to the ingredients that I have specified as my preference.

\Vhat I claim is:

1. A refrigerator or cabinet, having in combination a box structure, a binder material spread over the exterior of the box structure, a web of flexible material spread over the binder, and a frangible material carried on the outside of the -web.

2. A refrigerator or cabinet, having in combination a box structure, a binder spread over the exterior of the box structure, a Web material spread over the binder, a frangible material carried on the outside of the web, and a finishing coating over the frangible material.

3. A cabinet or refrigerator, having in combination a box structure, a binder spread ()"81 the exterior of the box structure, a fabric spread over the binder, and an artificial stone coating carried on the outside of the fabric, substantially as described.

4. A cabinet or refrigerator], having in combination a box structure, a binder spread over the exterior of the box structure, a fabric spread over the binder and united thereto, and an artificial stone coating spread over the exterior of the fabric and united thereto, and a finishing material on the exterior of the stone coating.

5. A cabinet or refrigerator, having in combination a box structure, a coating of stone work spread over the outside of'the box structure, a web material imbedded in the stonework coating, a second stonework spread over the outside of the web.

(3. A cabinet or refrigerator, having in combination a box-like structure, a binder spread over the outside of the box-like structure, a muslin fabric spread over the binder and united thereto, a coating of stonework spread over and united to the outside of the muslin.

7 A cabinet or refnigerator, having in combination a box-like structure, a binder spread over the outside of the box-like structure, an exterior coating and an intervening reinforcing material between the binder and the exterior coating.

8.\ A coating for wood or similar materials, comprising a base of wood, a binder, afabric spread over the binder, and a finishing material carried on the outside of the fabric and of a frangible nature.

9. A coating for wood or similar materials, having in combination with a wooden base a binder, a fabric spread over the binder, and an oxy-chloride cement coating spread over the fabric.

10. A coating for wood or similar materials, having in combination with a wooden base a binder, a fabric spread over the binder and imbedded therein, a coating of oxy-chloride cement in which the fabric is imbedded on the outside, and a finishing enamel covering the oxy-chloride cement.

. 11. A coating for wood or similar materials, having in combination with a wooden base an oxy-chloride cement spread over the wooden base, a fabric laid over the cement and imbedded therein. and a second coating of oxy-chloride cement laid over the fabric in which the fabric is also imbedded.

12. A coating for wood or similar materials, having in combination with a base material, a cement coating, a fabric laid over the cement, a second cement coating laid over the fabric in which the fabric is imbedded between the two coats of cement.

13. A coating for wood or similar materials, having in combination a base material, a binder laid over the base material, a fabric spread over the binder and imbedded therein, and a coating of frangible material laid over the fabric in which the fabric is imbedded between the two coats of material.

14. A method of finishing refrigerators or cabinets which comprises spreading a binder over the cabinet, the laying of a fabric in the binder while still wet, then the coating of the fabric with a frangible material while in a fluid or plastic state.

15. A method of covering a refrigerator or cabinet, comprising the spraying of an oxychloride cement over the exterior of the sanie, the laying of a fabric over the coating of cement while still wet, and the spraying of a second coating of oxy-chloride cement over the fabric.
